“What makes it?” I pursued.
“Well, you know radium rays will make a diamond fluoresce in the dark.”
“Yes,” I objected, “but how about those in the comb?”

It was indeed a shame to take advantage of Miss Wallace’s loyalty to Denison, but she was so game about it that I knew only the utmost necessity on Kennedy’s part would have prompted him to do it. She had a key to the office so that it was not necessary to wait for Denison, if indeed we could have found him.

“No. Only Mr. Denison has that. What are you going to do to protect the safe to-night?” she asked.
“Nothing especially,” evaded Kennedy.
“Nothing?” she repeated in amazement.
